Unscented Kalman filter (UKF), on the other hand, can also deal with nonlinearities in the system dynamics by approximating the state probability distribution with deterministic sigma points. The sigma points are then propagated through the non-linear functions, from which a new mean and covariance estimate are then formed.

Appendix K The Unscented Kalman Filter (UKF) The unscented Kalman filter (UKF) is based on the “unscented transformation” (UT). The unscented Kalman filter (UKS) presented in Reference [11] can be understood as an approximate implementation of this form of smoother in nonlinear systems. The resulting GP-UKF algorithm has a number of advantages over standard (parametric) UKFs.
